Pulmonary arteriovenous malformations (PAVM) represent pulmonary vascular anomalies and in majority of cases are congenital in origin. We report a case that presented with predominant complaints of dyspnoea on exertion and cyanosis. Clinical examination revealed a bruit in the left lower interscapular and infrascapular areas which led us to suspect PAVM. The diagnosis was established on the basis of computed tomography (CT) thorax with three-dimensional virtual reconstruction technology (3D VRT) images and pulmonary angiography. Patient was successfully treated by embolotherapy using steel coils, which resulted in 90% exclusion of the aneurysm from the rest of the systemic circulation.
